Teddy stopped a little way away from Hermione, still smiling boardly. Okay so she didn't recognise him, but he'd all but expected that. She looked so young. Younger than he'd ever known her, so it stood to reason that she wouldn't recognise him. "I'm Teddy Lupin," he explained. He laughed, raising his hands in mock surrender as she tightened her grip on her wand. "Don't worry, I come in peace." He grinned.
"My dad's Remus," he said, just to reiterate who he was, if his name didn't ring any bells.
